why do people gain weight after gastric bypass surgery

Now that a third of Americans are obese, doctors are working to treat the problem using a variety of methods and tools. One such way is bariatric surgery, but new research suggests that one common form of the procedure doesnБt automatically keep the weight off. The research, published Wednesday in the, examined long-term effects of laparoscopic sleeve gastrectomy. The researchers concluded that after five years, nearly half of patients experienced significant weight gain. Laparoscopic sleeve gastrectomy, or LSG, has become a popular weight loss surgery in the United States because itБs covered by major insurance carriers. The procedure removes the majority of a patientБs stomach, resulting in a tube-like structure about a quarter of its original size. Besides weight loss, the surgery has been shown to reduce a patientБs risk of diabetes, high cholesterol, and hypertension. Patients who are obese and have one of these other conditions are often candidates for LSG and other bariatric surgeries. LSGs to be effective for short-term weight loss in 90 percent of young patients. It also reduces their risk of other serious conditions by 70 percent in the first two years after their surgeries. that itБs a superior weight-loss tool to other surgeries, like laparoscopic adjustable gastric banding. But the new research suggests that the surgery alone isnБt enough to benefit obese patients in the long run.


The surgical process may be irreversible, but its protective effects arenБt necessarily permanent. Dr. Andrei Keidar, of Beilinson Hospital in Petah Tikva, Israel, and his colleagues, examined data from 443 patients who underwent LSGs from the same surgical team, between 2006 and 2013. Researchers found that while excess weight loss was at 77 percent after a year, it decreased to 56 percent after five years. Diabetes remission was promising at 51 percent after a year, but only 20 percent after five years. Remission of hypertension, however, remained steady at 46 percent from the first to fifth year. БThe longer follow-up data revealed weight regain and a decrease in remission rates for type 2 diabetes mellitus and other obesity-related comorbidities,Б the study authors concluded. БThese data should be taken into consideration in the decision-making process for the most appropriate operation for a given obese patient. Б
Despite the findings, Keidar says bariatric surgery is still the best currently available weapon against morbid obesity, but it shouldnБt be taken as a Бpanacea. Б БThe first year after surgery is usually a Бhoneymoon period,ББ Keidar told Healthline. БThat time should be used for coining new habits.


Б These habits include proper diet, regular exercise, and avoiding other unhealthy habits that may interfere with those, including smoking and excessive drinking. Dr. Bruce Y. Lee, director of the Global Obesity Prevention Center at Johns Hopkins Bloomberg School of Public Health, says the latest study is further evidence that there is no single Бmagic solutionБ to obesity or shortcut to weight loss, Бdespite what advertising and some popular beliefs may suggest. Б БBariatric surgery alone is often not effective,Б he told Healthline. БPatients must also incorporate substantial lifestyle and behavior changes along with the surgery to achieve sustainable weight loss. Б Knowing this, responsible surgeons must make sure surgery candidates are also willing and able to make the necessary dietary and physical activity changes before agreeing to operate on them, said Lee, who was not part of the new research. БIf the patient cannot maintain these behavioral changes, then the weight will frequently come back,Б he said. БWhile bariatric surgery can be helpful for people who have tried and exhausted all other options, we must realize that such surgery is no replacement for changing the systems that lead to obesity. Б б Gastric bypass surgery enables patients to lose weight more rapidly and reliably than diet and exercise alone.


In addition, it's been shown that symptoms of weight-related ailments, such as Type 2 diabetes, often improve quickly after surgery. Obviously, the benefits of successful gastric bypass surgery can be immense. But what happens if the surgery is not successful? Does it fail often? What should you do if it does? Gastric bypass surgery involves two steps: one "restrictive" step, where the doctor surgically shrinks the stomach and restricts its ability to store a lot of food, and one "malabsorptive" step, where the doctor reroutes the intestinal tract in such a way that the body absorbs fewer calories (and fewer nutrients) than before. These modifications are in place for the duration of the patient's life. Sometimes the restrictive step can gradually lose effectiveness if a patients stomach stretches back out over time. P The small pouch created by the surgeon can gradually get bigger, enabling the patient to eat more and possibly erasing the weight loss and health gains that the patient has experienced. P Typically, this can be caused by lack of attention toPproper dietPand portion size. In any event, if the patient gains weight back, there are steps to take to halt this weight gain and get back on the path of weight loss.


The first thing to do if you find yourself regaining weight after weight loss surgery is to make an appointment with your weight loss surgeon and his clinical team. Together, you can examine various factors, starting with your nutritional program. P It is essential that you continue to pay attention to your diet over the long term; Pif you find that you have gotten more permissive with high-calorie food or with portion sizes, that is the likely first thing to correct. In some cases, revision surgery may be recommended. There are procedures you can undergo to re-shrink the stomach. One common revision surgery is theP, which can shrink the stomach without the need for incisions. Some gastric bypass patients opt to have aPlap-band placed on their stomachPto create that small pouch. and Marina Weight Loss can explain these procedures if you turn out to be a good candidate, or you can find information elsewhere on this web site.
